Ingestion of solid food by plasma membranes is called

Options

A. Endosmosis
B. Pinocytosis
C. Cytokinesis
D. Phagocytosis

Answer

To answer the question "Ingestion of solid food by plasma membranes is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about the process by which cells ingest solid food through their plasma membranes.

2. **Analyze the Options**: We have four options to consider:
- A) Ando osmosis
- B) Pinocytosis
- C) Cytokinesis
- D) Phagocytosis

3. **Evaluate Each Option**:
- **A) Ando Osmosis**: This term seems to be a misnomer. The correct term is likely "osmosis," which refers to the movement of water across a semi-permeable membrane, not the ingestion of solid food. Thus, this option is incorrect.

- **B) Pinocytosis**: This process refers to the ingestion of liquid material by cells, often described as "cell drinking." Since the question specifies solid food, this option is also incorrect.

- **C) Cytokinesis**: This term refers to the division of the cytoplasm during cell division, not the ingestion of food. Therefore, this option is incorrect.

- **D) Phagocytosis**: This is the correct term for the process where cells ingest solid particles or food. It is often referred to as "cell eating."

4. **Conclusion**: Based on the analysis, the correct answer to the question is **D) Phagocytosis**.

### Final Answer:
Ingestion of solid food by plasma membranes is called **Phagocytosis**.
